ROSS VAUGHAN, PET'ISBURGH, PE'BHWSYLVANIA, ASSIGNOR TO THE EX-EL GOM- EANY, OFZPITTSBURGH, PENNSYLVANIA, A CORPGBATION 0F DELAWARE COIN-CONTROLLED VENDING- MACHINE.

Application filed November 20, 1920, Serial No. 425,377.- Renewed Apr11 i4, 1925.

To all whom it may com-amt:

Be it known that 1, Ross VAUGHAN, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Coin-Controlled Vending Machines, of which the fol lowing is a specification.

My invention relates to coin controlled vending machines.

The principal object of this invention is to provide an improved means for closing the coin-slot when the article magazine 1s empty or the machine parts are not in the normal position for receiving a coin. Another object is to provide means for rejecting coins of insufficient diameter or weight. Other objects appear hereinafter.

Referring to the accompanying drawings, Fig. 1 is a fragmentary view showing certain parts in elevation and other parts in vertical section; Fig. 2, a fragmentary view of the same parts as are in Fig. 1, but rotated toward the observer ninety degrees, parts being in horizontal section; Fig. 3, a section on the line TIL-III of Fig. 1; Fig. 4, a section on the line IVIV of Fig. 1; and Fig. 5, a perspective view of the coinactuated locking-lever for the delivery devices.

The machine has a casing, of which only the front 1 is shown, the other sides being readily understood and supplied. The front has the rectangular opening 2 closable by the door 3 which is the front side of the article-delivery device. This device has the bottom 4 attached to the door 3 at its lower edge and extending into the casing through the opening 2. The door 3 and the bottom 4 meet at slightly less than ninety degrees so that the bottom slants downwardly slightly toward the door. The delivery device has the end members 5 connected to the door and the bottom and standing close to the ends of the opening 2. The hinge rod 6 passes through the ends 5 and lies in the angle between the door and bottom member of the delivery device. The ends of the rod 6 are non-rotatable in the blocks 7 secured to the inner face of the front 1. The coiled spring 8 surrounds the rod 6 and has one end secured to the rod at 9 and the other end provided with the extension 10 lying on the bottom 4.

11 represents the article magazine or runway which lies back of the delivery device and has its upper surface inclined toward the said device and arranged so that round articles, as bottles, lying on their side may roll by gravity down thereon and on to the bottom 4. The bottom 4 has a curved downward extension or lip 12 at its rear edge. The delivery device is of such size as to receive one article 13 or quantities of goods to be delivered for one coin. When the delivery device has been swung outwardly, as

in Fig. 4, the lip 12 holds back the next article 13 on the runway 11. When the article 13 in the delivery device has been removed, the spring 8 returns the device. to its normal position, in which the lip 12 is below the top of the runway 11, whereupon the second article 13 is released and permitted to roll into the said delivery device, and the articles 13 in the rear to roll down the runway for a distance equal to the diameter of one of the articles.

One of the ends 5 has close to the inner face of the front 1 the vertical locking slot or notch 14 to receive one end of the locking lever 15 pivoted to the front on the pivot 16. They other end of the lever has the fork members 17 which lie beneath the opposite edges of the vertical coin chute 18. The members 17 are spaced apart so as to retain thereon a coin of appropriate size for operating the lever 15, but to allow smaller coins or disks to drop between them. lVhen the proper coin falls upon the lever 15, the lever rocks just sufficiently to move the lever out of the notch 14 but not enough to release the coin. The lever is stopped by its engagement with the inwardly and upwardly inclined lug 19 supported on the inner face of the door 3. When the lever 15 rests against the lug 19 it is free from the notch 14 and stands in front of the camshaped upper edge .22 of the adjacent end 5 of the door. When the door 3 is pulled forwardly by engaging the hand pull 23,

the cam 22 rocks the lever 15 so as to lower Beneath the bottom 4 is the lever 26 having the end farthest from the coin chute fulcrumed on the pivot 27. The other end of the lever is connected by the link 28 to one end of the lever 29 ivoted between its ends on the pivot 30. T e other end of the lever is arranged to be moved so as to lie between the coin'chute 18 and the coin-slot 24. The lever 26 has a lug or projection 31 adapted to extend up through the opening 32 in the bottom 4 of the article-delivery device. When an article 13 is in the said delivery device, it rests on the In 31 and holds the lever 26 down with the ug flush with the upper face of the bottom 4. When the lever is so held down the lever 29 is held from closing the coin-slot 24. Whenever the article device is swung outwardly, the article 13 which was previously resting on the lug 31 vis moved awa from the lug, whereupon the spring 33 rocii s the lever 29 so as to close the com-slot. When the delivery device returns to its normal position, another article 13 rolls into it and upon the lug 31, causing the lever 26 to rock the lever against the tension of the spring 32 so as to open the coin slot. When the last article 13 has been removed from the machine, the lever will keep the coin slot closed after the door has been closed. Thus the coin slot will be closed at all times when the delivery device is not in normal or closed position and when there is no article 13 on the lug 31 due either to'the want of articles in the machine or to the accidental failure of an article to roll from the runway to the delivery device.

I claim:

In a coin-controlled vending machine, a casing having a front openlng, a door hinged at the bottom of the opening and adapted to close the opening, an article support connected to the lower portion of the door and projectin into the casing, a lever pivoted at one on to the casing and havmg a projection extending through the article-support and above its upper surface and adapted to be depressed by an article resting on the support, a coin slot, means to close the slot, and means tending to close the slot but prevented from so doing by the lever when depressed, the said bottom lifting the article from the projecting meansat each operation of the door 111 opening' slilgned at Pittsburgh, Pa., this 17th day of ovember, A.- D. 1920.
